Strengthening the competitiveness of its range of freecooling chillers, Kaltra has introduced in the market the new Lightstream Scroll II with refrigerant R454b. These chillers are the latest in an array of innovative products to help users stay one step ahead of rising energy costs and increasingly stringent environmental legislation.
Condensation management is essential to ensuring the efficient function of heat exchangers and critical for the correct operation of evaporators.
Hydrophilic topcoats, surfaces tending not to adsorb water or be wetted by water, are effective in environments of excessive condensation, as they enable water to flow easily off the heat exchanger surface by virtue of lowered surface tension, thereby enhancing heat transfer performance in wet and frost conditions. At the same time, hydrophilic coatings protect heat exchangers from the corrosive effect of water and exhibit fine performance in providing protection in salty environments.
